Puget Sound Traction, Light & Power Company was incorporated in January 1912 and was responsible for the operation of several Puget Sound interurban railway lines. In addition to their passenger lines, Puget Power provided freight services to regional businesses and industries such as the Renton coal-mines owned by Puget Sound Electric Railway. As automobiles became more prevalent during the 1920s, the company reincorporated in 1919 as Puget Sound Power & Light Company in response to the gradual demise of the railroad passenger industry. The subsidiary company Pacific Northwest Traction began offering bus services between Seattle and Bellingham from 1925 onwards. When use of the railway interurban gradually declined between 1928 and 1939, Puget Power began to focus its interests on the distribution of power in the Puget Sound region and began its acquisition of Washington utility companies.
